Abstract
A water soluble naphthenate emulsion (trace element fertilizer) for spraying on leaves of horticultural crops and its preparation method are disclosed. The emulsion consists of naphthenate, organic solvent and surfactant. When naphthenate is produced, water is used as diluent instead of organic solvent, so that it is simple in production process, convenient for application, and after the emulsion is added with water, it can be directly sprayed by using general sprayer, and its yield-increasing effect is obvious.
Description
The invention belongs to liquid trace element fertilizer scope.
Horticultural crops such as citrus, grape, apple all need micro-nutrients such as zinc, molybdenum, iron, manganese, copper.If the trace element that soil is supplied with is not enough or be the form that can not utilize, lack required nutrient in the crop growth process just can make, fruit quality occurs and descend, the situation that output reduces.For example: in calcareous or salt marsh soil, fruit tree is just very general because of " little leaf " phenomenon that scarce zinc causes.So far, normally use the way of the inorganic little fertilizer of foliage spray (as zinc sulphate) to solve.But adopt this way to be subject to climatic effect, the nutrient of sprinkling is often fallen by rainwater drip washing or wind, is difficult for being plant absorbing.Add sodium hydroxide or limewash and can produce precipitation again, generate other compound and remain on the blade face, hinder the metabolism of crop and the absorption of nutrient.In recent years, Japan Patent (special public clear 50-34943) and United States Patent (USP) (USP4243676-1981) have been introduced a kind of oil-soluble naphthenate (as zinc naphthenate) organic liquid fertilizer that is used for the foliage spray of fruit culture crop, have improved little fertile effect of using.But in the process of making this oil-soluble naphthenate, be easy to carry out, need to add a large amount of methyl alcohol, the thinner of xylene solvent for reacting for making operation.Reclaim above-mentioned solvent at last again in the distillation procedure process, make the production process complexity, operating environment worsens, and has increased energy consumption.Simultaneously, naphthenate need add carrier oil again and is mixed with the oil-soluble spray.And this spray is still needed and is carried out foliage spray with special ultra low volume spraying device, and cost is higher, and is not easy to operate, uses improperly can produce poisoning, and popularization is restricted.
The objective of the invention is to above-mentioned oil-soluble naphthenate spray trace element fertilizer method for making and the problem of using existence are improved, it is simple to develop a kind of technology, and cost is lower, uses water-soluble easily naphthenate emulsion trace element fertilizer.
Method for making of the present invention is to be reaction diluent with water, and adopting molecular weight is that 200～660 naphthenic acid (also can be represented with milligram KOH/ gram value; Before the use, when containing phenol in the tartaric acid, need carry out oil removing distillation handles) carry out saponification, metathesis reaction with the aqueous solution of one or more salts of metals such as alkali metal hydroxide and zinc, molybdenum, iron, manganese, copper, obtain the reactant of forming by organic facies and water.Most moisture is to separate from the aqueous phase that contains sodium sulphate.Small amount of moisture in the organic facies just obtains naphthenate after treatment.Add organic solvent, surfactant, be mixed with water-soluble naphthenate emulsion trace element fertilizer at last, by product sodium sulphate obtains through freezing behind distillation moisture.Reaction temperature in the naphthenate manufacturing is 65～95 ℃, and saponification and metathesis reaction time are 0.5～2.5 hour.The equivalent proportion of metal and naphthenic acid is 1～20.The alkali metal hydroxide that saponification is used can be used sodium hydroxide, also can use potassium hydroxide, the most handy sodium hydroxide.The slaine of zinc, iron, manganese, copper can be a metal chloride, also can be metal sulfate, the most handy metal sulfate.Diluent water can be general water or treated water during the system naphthenate, and the water yield of interpolation is 50～300%(weight of naphthenic acid).Solvent can be lower alcohol (methyl alcohol, ethanol, a cyclohexanol), aromatic hydrocarbons (toluene, dimethylbenzene), and kerosene in one or more.Surfactant can be nonionic surface active agent or anionic surfactant or their two kinds of compositions.Nonionic surface active agent can be wherein one or more such as polyoxyethylene 20 sorbitan monooleate, polyoxyethylene 20 sorbitan monostearate, Aceonon 300 MO, polyoxyethylene fatty alcohol, polyoxyethylene cetyl alcohol, castor oil APEO, polyoxyethylene vegetable oil, phenethyl phenol APEO, alkylphenol polyoxyethylene.Anionic surfactant can be wherein one or more such as calcium dodecyl benzene sulfonate, glyceryl monostearate, polyoxyl 40 stearate enuatrol.In the emulsion trace element fertilizer, organic solvent accounts for 10～65%(weight), surfactant comprise 5～20%(weight), naphthenate accounts for 20～70%(weight).Can make the alkaline water dissolubility naphthenate emulsion trace element fertilizer that contains zinc, molybdenum, iron, manganese, copper according to the method described above.
Advantage of the present invention is: in making the naphthenate process, be reaction diluent with water, saved a large amount of methyl alcohol, dimethylbenzene organic solvent, need not the solvent recovery operation.Simplify technology, improved the operation environment, reduced the pollution of noxious material, reduced product cost.Available common sprayer unit sprayed after the emulsion of making added water, and nutrient evenly, does not produce precipitation, is easy to by plant absorbing, and is easy to use, is convenient to promote.
Example
With acid number is that naphthenic acid 112 grams that 183 milligrams of KOH/ restrain add in 500 milliliters of there-necked flasks that have agitating device with 100 ml waters, and then adds 15 grams, 368 millinormal sodium hydroxide.Intensification Jia Re And fully stirs.Under 85 ℃ reaction temperature, reacted 1.5 hours, continue to add 30 grams again, 184 millinormal zinc sulphate continue reaction 1.5 hours, after fully stirring, in the separatory funnel with 1000 milliliters of reactant liquor impourings, standing demix.After isolating the aqueous layer that contains sodium sulphate, aqueous layer is carried out concentration and evaporation and freezing and crystallizing, reclaim sulfuric acid sodium by product.After from the organic layer that contains zinc naphthenate, removing remaining small amount of moisture, add kerosene, xylene solvent, calcium dodecyl benzene sulfonate anion surfactant and castor oil APEO non-ionic surface active agent can make water-soluble zinc naphthenate emulsion.Wherein, solvent accounts for the 52%(weight of emulsion), the 9%(weight of surfactant comprise emulsion), zinc naphthenate accounts for the 39%(weight of emulsion).Contain Zn3～4%(weight in the emulsion).After the apple tree that suffers from " little leaf " sprayed made zinc naphthenate emulsion, blade zinc content and output were shown in table one, table two.
